AP BIOLOGY

Detailed explanation-1: -Biological diversity comprises three levels: Species diversity: the variety of different species; Genetic diversity: the variety of genes contained in plants, animals, fungi and micro-organisms; and ecosystem diversity: all the different habitats that exist.

Detailed explanation-2: -Usually three levels of biodiversity are discussed-genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species.

Detailed explanation-3: -Biodiversity is commonly broken down into three levels or types: genetic diversity, species diversity, and ecosystem diversity.

Detailed explanation-4: -It occurs at 3 different levels, namely, species diversity, genetic diversity and ecosystem diversity. Each individual has a unique genetic architecture, which is determined by the hereditary material-DNA.

Detailed explanation-5: -Genetic diversity, species diversity and ecosystem diversity are three important components of biodiversity. Genetic diversity takes into account the genetic variations present in a species whereas ecosystem diversity refers to types of ecosystem present on earth. Species diversity refers to species richness.
